Why are old people so fragile?

There are many reasons why older adults may be more fragile than younger adults. These include:

- Age-related changes in body composition. As people age, they lose muscle mass and gain fat mass. This can lead to a decrease in strength and mobility, and make older adults more susceptible to injury.

- Age-related changes in the immune system. The immune system becomes less effective as people age, which makes them more susceptible to infection.

- Age-related changes in the cardiovascular system. The heart and blood vessels become less elastic as people age, which can lead to high blood pressure and other heart problems.

- Other chronic conditions. Older adults are more likely to have chronic conditions such as diabetes, arthritis, and cancer. These conditions can further increase their risk of fragility.

It is important to note that not all older adults are fragile. Many older adults are healthy and active, and they enjoy a high quality of life. However, it is important to be aware of the factors that can contribute to fragility in older adults, and to take steps to reduce the risk of becoming fragile.
